WINDOW-CLEANING DEVICE.

Application filed March 9, 1916. Serial No. 83,116.

- a window cleaning device which is provided with a sponge or similar porous member for holding a cleansing liquid and a strip of rubber or other elastic material for drying the window after the cleansing liquid has been applied thereto.

The principal ob ect of my invention is cleaning device in be readily attached and detached and in which the sponge may be securely attached so that it will not be torn from the holder when in use. a

A further object of my invention' is to provide a construction carrying the sponge and rubber is made up of a single piece of sheet metal, providing a strong and at the same time a simple and inexpensive article.

The above and other objects and the novel features of my invention will be apparent from the following description taken in connection with the drawing in which,

Figure 1 is a perspective view of a window cleaning device embodying my invention. Fig. 2 is a perspective view of a part of the same showing the sponge and its holder partly withdrawn. Fig. 3 is a cross-sectional view of another device embodying my invention and Fig. 4 is a view showing the sponge and holder of the cleaning device of Fig. 3 being removed or inserted.

Referring to the drawings, the cleaning device shown in Figs. 1 and 2 comprises a single continuous sheet of metal having one longitudinal edge thereof provided with a double reverse bend on the under side of the body of the holder forming a groove 10 adapted to receive one longitudinal edge of the strip of rubber 11 which is used for removing the excess water from the window. The lower side 12 of the groove is pressed into the rubber-strip 11 sufficiently to securely clamp the strip in the groove. The sheet of metal is :bent along the line 13 to provide a Window in which the head 20 and extends beneath whereby the portion forming the groove 10 is inclined downwardly at. a slight angle so that when the tool is used for drying, the rubber portion thereof will be disposed substantially normal to the surface to be dried.

Intermediate its ends the sheet metal blank is doubled on itself twice to form the sides or jaws 14 and 15 which are spaced apart a sufficient distance to form a sponge receiving channel 16 between them. It will be noted that the side members 14 and 15 have their upper ends bent toward one another as at 1411 and 151 so that the distance between the upper edges thereof will be less than the width of the bottom 18 of the channel 16. Two bars 19 are sildable endwise into the channel 16 and are held in place by the inturned edges 141 and 151. Rows of pins 191 carried by the bars 19 pass through the sponge in said channel and secure the sponge to the bars 19. It will be understood that any other suitable securing means may be employed.

, The part 22 of the sheet metal plate beyond the sponge groove is bent at the point the bottom 18 of the channel and beneath the plane portion 21 of the body of the holder located between the rubber groove and the sponge channel, thereby stifi'ening said part 21. The edge 23 of the part 22 of the body of the holder extends in between the top side 24 of the groove 10 and the downwardly inclined part 25 of the body. The edge 23 is clenched in place by pressing the double reverse bend approximately along the bend line 13.

From the foregoing description it will be seen that the body of the holder is of double thickness throughout, the plane portion thereof constituting the portions 21 and 22 between the rubber groove and sponge channel being of two thicknesses and therefore of greater rigidity than if only one thickness were employed. This is of advantage to prevent distortion of the body when angular pressure especially is applied to the rubber strip 11. A tubular shank 26 is secured to the under side of the body beneaththe channel 16 and is adapted to receive a pole or handle of suitable length by means of which the cleaner is manipulated.

Another window cleaning device embodying my invention is shown in Figs. 3 and 4. In that form of device one edge of the body plate may be provided with a double regroove 10 and its other edge fits against the a under side of the rubber strip 11. The strip 111 is clamped against the rubber strip 11 bV a plurality of bolts 112 spaced along the reverse bend and extending through the latter, the strip 11 and the plate 111. The

rubber strip 11 is therefore detachable so that the rubber may be renewed when worn out. The opposite longitudinal side of the.

plate is bent upwardly as at 28 and then inwardly as at 29 forming one jaw or side of a sponge receiving groove 30. The opposite side of the channel 30 consists of a separate piece of metal having an upwardly extending part 31 parallel to the part 28 of the main body and an inwardly extending edge 32 opposite the edge 29. The separatejaw member having the side 31 and inwardly bent part 32 has, a base portion 33 resting on top of the plane portion 34 of the body of the holder. The base portion 33 and the body portion 34 are provided with similar pairs of slots 35 and 36 fitted with bolts 37 by means of which the movable side 31 may be adjusted with respect to the side 28 and clamped in adjusted posi tion. The sponge 17 may be held in place between the side members 28 and 31 by means of a series of pins 38 projecting from the opposing faces of the bars 39 and 40. The bars 39 and 40 fit in the channel 30 and are located between the bottom thereof and the outer edges formed by the inwardly extending flanges 29 and 32 on the jaw members. The prongs or pins 38 are adapted to engage into the portion of the sponge between the bars and will secure the sponge in the channel when the side bar 31 has been clamped against the bar 39.

' Having thus described the invention, what is claimed and desired to be secured by Letters Patent is:

1. A window cleaning device comprising a sheet metal holder having jaw members forming a sponge receiving channel, the

outer edges of said jaw ,members being closer together than the bases thereof so as to hold said sponge in place in said channel, a bar fitting in said channel and inclosed in the space between the bottom thereof and the top edges of said jaw members, said bar carrying prongs adapted to engage in a sponge and secure the same in said channel, and means for connecting a handle to the under side of said holder.

2. A, window cleaning device comprising a holder for carrying a strip of rubber and sponge at opposite longitudinal edges thereof, said holder' being made of a'single sheet of metal having one longitudinal edge thereof provided with an outwardly facing groove to receive one edge of said strip of rubber, the portion intermediate the ends of said sheet of metal being twice doubled on itself to form the spaced sides of a channel to receive said sponge, a portion of said sheet of metal beyond said channel being bent beneath said channel and terminating adjacent said groove, whereby the part of the holder between said sponge channel and rubber groove is of a double thickness of metal.

3. A window cleaning device comprising a holder for carrying astrip of rubber and a sponge at longitudinal edges thereof, said holder being made of a single sheet of metal having one longitudinal edge thereof provided with a groove to receive one edge of said strip of rubber, the. portion intermediate the ends of said sheet of metal being twice doubled on itself toform the spaced sides 01' j aws ofa channel to receive a part of said sponge, the upper or free ends of said sides or jaws being closer together than the bases thereof so as to securely hold the sponge, a portion of saidvsheet of metal being bent beneath said channel against the under side thereof and terminating adjacent the rubber receiving groove, whereby the part of the holder between the sponge channel and the rubber groove is of a double thickness of metal to stiffen the holder.

In testimony whereof I aflix my signature.
